Recently, the health issues triggered by fine dust matters occurred in higher frequency. Having adverse effects on health, particulate matters affect the human body indoors as well as outdoors. There is thus a need for a system to measure the concentration of particulate matters and control harmful particulate matters for human health in the indoor spaces where people live. The present study applied Internet of Things(IoT) technologies in order to increase the efficiency of the conventional fine dust measurement system. Especially, for the bidirectional communication environment, directly construct a separate server and applied to the system instead of a free cloud server also we used it directly in the school lab and home. When the proposed system is used in schools and homes, it can recognize the indoor environment quickly and it is expected that this will gradually contribute to the health of the individual. Users can also check the server data outside and deal with the current indoor situations.

In this paper we describe an efficient and easy to use internet stopper, which is called AINS (Automatic Internet Stopper), which uses ARP spoofing scheme. Instead of forwarding packets to router for the case of hacking, in ARP spoofing, the AINS ignores all the packets so that internet stopping operates. The AINS program needs to be installed only in manager computer that does not require additional agent program. In addition to setting manually the stopping computer list, it is able to indentify network nodes automatically by analyzing broadcasting packets. The experimental results show that less than 4 secs for spoofing interval is enough for blocking internet usage regardless the number of computers and therefore network overhead is negligible. The AINS can indentify and control network nodes not only on same subnet but also on different subnet only if they are connected onto same ethernet switch physically. It is being used for an efficient tool for controling internet usage of university computer laboratory and also for an efficient network management.

Background and Goals: This study set out to apply the Theory of Planned Behavior (TPB), which is known to provide good explanations about human behavior, and test it to see if it could predict safety behavior by affecting the intention for safety behavior and perceived behavioral control and if intention for safety behavior would be influenced by attitude toward behavior, subjective norm, and perceived behavioral control. Methods: The subjects were 98 dental technology majors in D City. The questionnaires were distributed, filled out and collected on the spot. Each item was measured on a seven-point scale, and it's interpreted that the higher mean of each item would translate into safety behavior. Results: The analysis results of the Theory of Reasoned Action (TRA) variables indicate that only subjective norm ($\beta$ = .528, p < .000) had explanatory power of 27.2% (F = 37.170, P <.001) for intention for safety behavior. The results show that subjective norm and attitude toward behavior affect intention for safety behavior. The analysis results of the TPB variables revealed that intention for safety behavior had explanatory power of 26.6% (F = 36.072, p <.000) for behavior. When intention was added by perceived behavioral control, the explanatory power increased to 34.5% (F = 26.530, p <.000). And when it's added by knowledge, the explanatory power increased to 39.0% (F =21.661, p <.000). The results suggest that intention has the biggest influence on predicting safety behavior. Conclusion: The results show that the TPB model by Ajzen (1985) has greater forecasting power for intention and act of safety behavior than the TRA model by Fishbein & Ajzen (1980) and the TPB model can applied in the prediction of safety behavior. Thus safety behavior is considered as behavior whose determination control is limited. And safety education programs that add knowledge to the TPB variables will help the students promote their safety behavior.

In this paper, we have designed and implemented that PC management system has the function of monitoring and controlling system management MIB defined for PC management using SNMP in PC room. System management MIB consists of monitoring MIB for system and processor information and controlling MIB for backup and restoration. For this, we have added new defined MIB variables to standard MIB and displayed system information, processor information, backup and restoration information of managed PC. And the structure between management system and managed system is shown and process of system information, processor information, backup and restoration of managed PC is illustrated. On real environmental, by monitoring window version, CPU type, system memory and virtual memory and performing backup and restoration of managed PC, actual operation is tested. Management system gathers system information and processor information from managed system and performs backup and restoration for recovering fault of managed system. Hence PC managers can operate and manage many PCs on LAN, efficiently.

Objectives : The purpose of the study was to investigate self-reported oral health attitudes and behaviors among patients receiving scaling services and provide guidelines for developing preventive programs for dental disease. Methods : The survey was administered to a sample of 462 receiving voluntary scaling service in the practice lab in the department of dental hygiene at J health college. Results : 1. Of all participants, 261(56.5%) reported that they received scaling services in the past. 134 of the women (62.6%) and 127 of the men (51.2%) received scaling services 2. Analysis of the regular scaling attendance rates showed that only 16.2% of all participants received routine scaling. 13.7% of the male participants and 19.2% of the female participants received scaling on a regular basis. 3. Participants commonly reported "self-motivation" and "suggestion by others" (37.9% and 34.1%, respectively) as the main reasons for obtaining scaling services. 4. The main reasons for not obtaining scaling services were "I did not know about scaling" (39.3%), "I don't feel it is necessary" (27.4%) and "because I am scared" (20.9%). More men (42.1%) than women (35%) reported that they did not know about scaling. 5. Of the total participants, 41.6% reported that they were concerned about oral health at a moderate level, and 30.3% reported that they were concerned about oral health at a high level. 6. Of the participants who responded "very concerned about oral health" and "extremely concerned about oral health", the majority obtained scaling service (70.2% and 84.2%, respectively). Conclusions : The study suggested that researchers and national health authorities should develop routine scaling, preventive dental care, and oral health programs for oral health promotion and disease prevention.

The purpose of this study to provide base data of various dental hygiene management systems are necessary to improve the oral health of visitor oral prophylaxis practice units, investigating and analyzing the oral health behavior and awareness of 130 scaling patients who visited the oral prophylaxis practice units of J Health College from April to May of the year 2007. The following conclusions were obtained 1. 50% of them had more than 2 times of toothbrushing a day, and 45.5% had more than 3 times of toothbrushing a day. 2. Toothbrushing was done after having a breakfast in 75.4% and 71.5% brushed their teeth after having a dinner. As the time to brush teeth, 45.4% of the subjects spentless than 3 minutes and 39.2% of them spent less than 2 minutes, and 48.5% of them bushed their teeth in up and down directions and 43.8% used mixed approaches. 3. The usage period of a toothbrush lasted about 3 month in 33.1% and 26.2% used a toothbrush about 2 month, and 20% of the subjects had the experience of using dental floss or interdental brush. 4. 61.5% of the subjects had the experience of having scaling treatment. The frequency of scaling was found to be 38.5%. 5. As the cause of having caries of the teeth, 73.8% responded it as unfaithfully brushing and 50% the subjects considered smoking is very harmful to dental health. 6. The most important behavior for dental health was found to be not eating sugars that were pointed out by 75.4% of subjects. Based upon the above listed study results, various dental hygiene management systems are necessary to improve the oral health of patients who visit oral prophylaxis practice units, especially, the correct toothbrushing and periodic oral examination with preventive scaling were thought to be necessary.
